【Abstract】 A new fault-detection method is proposed in this paper.The newly developed method is compared with the existing ones,whose successful operation depend on checking the surge in single-phase current and phase to phase current difference.Also in this paper presented a new way of phase-select for faults through fault checking measurements.Dynamic model test`s results show that the proposed method has a series of advantages.更多还原
